The devil is always in the details, cars look like they are nearly finished when you get the major parts on, but thats not what takes the time.

because the pistons have been machined. why the need? people have obviously spent alot of time and money developing and making them so why does a spanner monkey with a lathe no better?
1st time ive seen one of these so called "the business" head gaskets and looks like they have that sealer milarky around the oil/water galleries/ cylinders? soon as any of it gives up the ghost something is gona come pissing out of somewhere? mgt be wrong but i dont think just because people read it on the likes of vauxsport and the savage price tag makes them good.
anyway yeah still alive........
hows tricks? you still bumming that rentboy?

Well ive used a cometic with no problems so i know they work 
Regarding the pistons there are quite afew people running them like im going to. So it looks like they are fine aswell but im no expert
Yer i let him have it every now and then  
Im good mate. Still doing the same shit so nothing has really changed. What about you?

Why not ?
The pistons have been designed so they can be machined to adjust compression ratio.
The mininum thickness has been measured, what is the problem ?
Most pistons have to be machined, does not matter what engine you build.
What is wrong with the cometic head gaskets ?
Many people use them for the LET/XE turbo engine without any problems, I use one on my Ford BDT and is used on other BDT engines which make A genuine 580 BHP from 1952cc engine.
There is a gasket made by HKS which is considered to be better, but is only available in standard thickness and cost £200ish.

What a load of bollox.
The Cometic and HKS gasket is tried, tested and proven.
You will have more trouble using a ZLET head gasket on a LET, you will get more corrosion and under boost conditions they go out of shape.
With regared the pistons, what do you think Omega would do if you asked for the same style pistons with a lower compression ratio ?
Thats right they would use a lathe or a mill to machine more metal from the piston bowl.
I would not sell or use any products that have not been proven or which I have had problems with, that is why I had parts made or altered, as examples, head studs, pistons to my design, ZLET oil pickups, gaskets, etc.

with regards to the head gaskets my opinion is that they are not tried and tested at all as most people on here seem to have done more engine rebuilds than ive had hot dinners. anyone done 50k on one??
not trying to start some kind of keyboard war here but still.
does the dome not have anything to do with the dissapation of fuel mixture/heat? thats what mahle claim with the pistons you get from regal?

Well ive been on abit of a spending spree that hasnt yet finnished lol
First off i brought a 2.5" 4 bolt to 3" V band adapter.
A High flow fuel filter
Some new brake discs
A Helmet hammock
A Fuel fillet bowl
A std fuel filter
some oil filters
Track rod ends
2 new Kumho NU31 tyres.
Crank senser
And a custom made exhaust silencer
Wile i was fitting the V band adapter i noticed that my dipstick tube and snaped :doh: Glad i spotted it now and not when it was all up and running.
Thankfully i had another on my old bottom end to replace it with.
Ive also had a mate of mine come round tonight and he has made a start on wirering in my Emerald 
He managed to get most of it done but he will be comming tomorrow afternoon to carry on.
Ive got some more wirering for him to do wile he is at it though lol Things like fuel pumps and some of the bits to go to the ECU like the shift light, Map switch and one or two other things.
Im still waiting on a price for my fuel lines........
Im still waiting for the rest of the car parts to be sprayed.......
Once i have done just about everything i will be taking the car over to Turbo Gavs for him to do the boost and exhaust pipes and wile its there we will properly get it up and running So then its ready to be maped.
Looking forward to that day!

I didnt do 50k no but the same gasket (2.0mm Cometic) Was put on and taken off my car about 6 times so id say it works. Torqued down and ran aswell.

No keyboard war just proven fact.
The middle lump is said to help squish, help the standard engine meet emmision laws, there are several different styles used, JE, Wisco, Omega, Cosworth, Mahle (look at the YB piston) they all make pistons without a lump in the middle, they all have made pistons for the LET engine without the middle lump.
Most engines on here and else where have not reached the 50K miles mark because they have developed problems elswhere, I have one engine aat 45K but that does not prove anything as it is only a phase 2/evo 5 spec engine.
Milage is not proof of reliability, the Cometic has been used on the XE/LET engine for nearly nine years that is actually more years than the ZLET gasket.
Components are often tested in competition that is part of the reason manufacturers enter motorsport.
The rallycross astra 580 bhp useses omega pistons machined in the same way from the same forgings.
If you do a dry build of an engine, measuring compression ratio, piston to valve clearance etc, piston machining is often needed, unless you are building a standard production engine.
Everyone is entitled to their opinions.
I you want more evidence just ask.
Good luck.
Steve

Looking good mate, coming together well
what size are the fittings on the fuel filter? I'm after some for mine, where you get them from?
Cheers
